Treemap Background Color

📊 Plotly Python

Hey,
No matter how much I tried, I do not succeed to change the background color of a treemap chart (gray). I am trying to make it transparent.
Does anybody have an idea?

fig = px.treemap(volume_by_category, path=['categories'], values='indexed_volume', color='indexed_volume', color_continuous_scale='Blues', width=1000, height=600)

fig.update_traces(name='categories', 
                  texttemplate="%{label}<br>%{value}<br>",
                  selector=dict(type='treemap'))

fig.show()

Hey there you need to set a fig. update_layout and add the following

paper_bgcolor='rgba(0,0,0,0)',
plot_bgcolor='rgba(0,0,0,0)'

Regards
